Spherical steam heat accumulator with wave guide guide mechanism

Abstract

The invention provides a spherical steam heat accumulator with a wave guide guide mechanism. The spherical steam heat accumulator comprises a spherical tank, and at least one wave guide stretches intothe bottom of the spherical tank from the top of the spherical tank and is spaced from the bottom end face of the spherical tank. A wave guide radar liquidometer is arranged at the upper end, exposedout of the top of the spherical tank, of the wave guide, and the guide mechanism for allowing longitudinal displacement of the wave guide and limiting transverse displacement of the wave guide is arranged in the spherical tank. The guide mechanism comprises a guide frame and at least one annular guide part. The guide frame is provided with at least one cross beam arranged in the spherical tank inthe transverse direction, and the annular guide part is arranged at the position, corresponding to the wave guide, of the cross beam. The wave guide can move in the longitudinal direction to penetrate the annular guide part. The spherical steam heat accumulator has the beneficial effects of being high in liquid level monitoring accuracy, reliable in operation, long in wave guide service life, convenient to mount and suitable for storing high-temperature and high-pressure liquid.

Description

technical field [0001] The invention relates to the field of steam storage equipment, in particular to a spherical steam heat accumulator with a waveguide guiding mechanism. Background technique [0002] In recent years, since the spherical tank structure has many advantages in engineering equipment, more and more steam heat accumulators adopt the spherical tank type. In the field of steam heat accumulator, the water level in the tank is a key parameter to be monitored during the operation of the steam heat accumulator. The commonly used spherical heat accumulator has a volume of 400m 3 and 650m 3 , The diameter of the spherical tank is as high as 9.2m and 10.7m, and the top-mounted guided wave radar level gauge is mostly used for liquid level measurement. The electromagnetic pulse emitted by the guided wave radar level gauge propagates along the steel cable, reaches the liquid surface in the tank, and obtains liquid level data through reflection. In order to avoid inter...

Problems solved by technology

However, this welding connection method is not suitable for spherical steam heat accumulators, because the working temperature of spherical steam heat accumulators fluctuates within a certain range during operation, the shell of the spherical tank will expand with heat and contract with cold, and the two ends of the waveguide are both Welded with the tank body 201 of the spherical tank, the welded joint at the joint produces tensile stress and compressive stress, and the waveguide is easily damaged
